Ab-monomers. I: Synthesis and polymerization of furyl-maleimide monomers

New AB-monomers containing either furyl and maleimide groups or hydroxy and acid groups were prepared by the reaction of 4-maleimidobenzoic acid chloride or 4-maleimidophenylisocyanate with 2-furfuryl alcohol or the Diels-Alder reaction of 4-maleimidobenzoic acid with 2-furfuryl alcohol, respectively. The structures of the monomers were confirmed by IR, 1H-NMR and elemental analysis. By Diels-Alder polymerization reaction or polycondensation reaction new poly(esther-imide) or poly(urethane-imide)s were prepared. Thermal curing behavior of monomers was investigated by DSC analysis. All polymers were characterized by elemental analysis, IR spectral studies and thermogravimetry.

Synthesis of novel thiol-reactive amphiphilic lipids based on cholesterol for protein-liposome coupling

The synthesis of a series of coupling lipids designed for covalently linking proteins to liposomes is described. The new compounds have in common a cholesterylsuccinyl unit as a lipid anchor and a thiol-reactive maleimidobenzoyl unit which are linked by alkyl or (poly)ethylene glycol spacers that differ in length and polarity.

Bioresponsive albumin-conjugated paclitaxel prodrugs for cancer therapy

The efficacy of traditional chemotherapy often suffers from rapid clearance and off-target toxicity. Drug delivery systems and controlled release are applied to improve the therapeutic efficiencies of smallmolecule drugs. In this work, two novel oxidative/reductive (Ox/Re) -sensitive and one non-sensitive Paclitaxel (PTX) prodrugs were synthesized with a maleimide group, which rapidly conjugates with albumin in vivo. Albumin serves as a good vehicle to deliver more prodrug to tumors due to the enhanced permeation and retention (EPR) effect. PTX was then released from the prodrugs in glutathione(GSH)/ reactive oxygen species(ROS)-rich tumor microenvironments. This bioresponsive prodrug strategy demonstrates potent chemotherapeutic efficiency in vivo and may be utilized in clinical cancer therapy.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1585-90-6 is helpful to your research. 1585-90-6

Antifungal activity of the methanolic extract and alkaloids of Glaucium oxylobum

The methanolic extract and total alkaloids of the aerial parts of Glaucium oxylobum exhibited good activity against Microsporum gypseum, Microsporum canis, Trichophyton mentagrophytes and Epidermophyton floccosum. Four alkaloids, dicentrine, glaucine, protopine, and alpha-allocryptopine, were identified as the compounds responsible for the antifungal activity of this plant.

Synthesis and characterisation of peripherally functionalised dendritic molecules

A number of peripherally functionalised dendritic molecules were synthesised in almost quantitative yield by a synthetic method involving the reaction between amines and isocyanates. The peripheral functional groups were incorporated by preparing a number of branched subunits, based on tris(hydroxymethyl)aminomethane (TRIS), 1, possessing three nitro, methoxy, methyl or maleimide terminal functionalities. Attachment of these branched units to the core molecules 4,4?-methylenebis(phenyl isocyanate) 13 and 1,3,5-benzene triisocyanate 20 afforded the corresponding dendritic molecules possessing 6 or 9 peripheral functional groups. Functional group conversions on the dendritic molecules have been successfully carried out, including hydrogenation of the terminal nitro to the corresponding amine and cleavage of the methoxy ether to give the corresponding phenol.
